opi-12K NOX,l OF MOUNT PLEASANT, IOWA.

LettcrePatent No. 61,343, dated January 22, 1867; i

IMPRGVED WASHING MACHINE.

' TO ALL WH'OM IT MAY CONCERN:

Be it known that I, C. H. KNOX,'of Mount Pleasant, in the county of Henry, and State of Iowa, have invented a new and useful improvement in Washing Machines; and I do hereby declare that the following isy a' full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings and lettersof reference marked thereon, making a.' part of this specification, in which- Figure 1 is a longitudinal elevation of my improvement, includinga part of the washing box, to which it is attached. i

Figure 2 is a sectional elevation of the same, including the washing apparatus.

FigureS is a sectional elevation taken transversely through the red lines z x.

The nature of my invention consists, iii-st, in clamping the gearing frame securely together,in order that the hot water used Vin the washing bo-x will not so warp. the lid of the box as to change'the position of the gearing-and render it inoperative, in combination with the described arrangement and application of 'a frictionroller to operate against the reciprocating segment and prevent the cogs from becoming detached from the pinion which operates the washing apparatus. The object to be gained by the use of my device is, first, the washing box can be lled alternately with hot and cold water, and not warp or curve the lid so este alfect the gearing; whichis not the case when the gearing is not clamped together, for when the lid is made convex on thev top, as when cold water is used, the segment is thrown away from the pinion, and when' hot wat-er is employed the top of the lid becomes convex, causing the cogs ofthe gearing to iit so closely that the washing .apparatus cannot be used; second, in consequenceof the outer sides of the frame being'mad'e solid-,the gearing attached thereto cannot either get out of place or interfere with the articles to be washed.

In order that others skilled in the art may he able to constructand use my device, I will describe the same. A is a section of the lidof the Ycommon washing machine, in which is permanently attached the bearing, B,

through which passes the vertical shaft C. F is the plate, which is let into the lid A, that supports the collars C, upon which the hollow shank I, of the pinion H, rests; the shaft C being prevented from falling down by means ofthe pin J passing through C, at the top of pinion H. K is the plate, which is secured tol lid A, and.

supports the lower end oi" the shaft N, to which the friction-roller L is attached; the upperrend of the shaft being supported by the projection M, on the part D, similar to the projection 0,011 D, which supports the npp r ond of shaft C. It willbe seen that the roller N fits closely against the segment P, and will prevent the pinion H from getting out of gear. rlhe segmentP is hung. upon the shaft R, and may have the proper reciprocating motion by means of the lever, shown at Q, iig. 1. Fig. 3 represents the extremities ofthe frame, DD', securely clamped together by means of the bar Tand screws S. The object of this clamp is to prevent the spreading of the frame D D. by the warping of the lid A. E shows the enlarged parts of the frameD D',

used for the purpose of covering the `pinion H and friction-roller L, so that they may not become entangled with clothing. W shows what I term a socket-plate, to which the washing apparatus Y Z is attached.' it isr the nut which is secured to the part Y, and holds the shaft C'to the reverse rotary apparatus Y Z.

Operation: When my device has been constructed as set forth, it can be operated similar to the same character of machines now. in use. The handleQ, attach-ed to the segment P, can be grasped by the hand, and worked back and forth in the customary manner, which will give the required motion to the parts Y Z.

Having thus fully described my device, what I claim and desire to secure by Letters Patent of the United States, is-

The bolt R, in combination with the clamp T, friction-roller L, plates K and F as set forth.
